+## Upgrading from 2.0 to 2.1
+
+Upgrading to Accumulo 2.1 is done by stopping Accumulo 2.0 and starting 
Accumulo 2.1.
+Before stopping Accumulo 2.0, install Accumulo 2.1 and configure it by 
following the 
+[Quick Start]({% durl getting-started/quickstart %}).

Review Comment:
   You could just as easily stop the 2.0 instance, install 2.1, run the upgrade 
utility, then start 2.1 instead of installing 2.1 prior to stopping 2.0.
   
   The upgrade utility shouldn't run on a live 2.0 instance, but on a stopped 
one. So, I think what's important is that the optional config upgrade utility 
needs to be run after stopping the 2.0 instance, but before starting the 2.1 
instance. I don't think it has anything to do with the order of installation 
relative to stopping the instance.
